MULTIPLE CELL REPRODUCING APPARATUS Application mea April 1, 192e. serial No; 351,747.

This invention relates to improvements inv but in which a plurality of such elements are disposed in such relation to the path of the modulated light rays that in case of the failure of .one or more of said elements to function the remaining elements will catch enou h of said rays to prevent interruption of t e operation of the apparatus.

With the foregoing and other objects in view, which will appear asthe description proceeds, the invention consists in the novel features of construction and combination of parts which will appear more fully hereafter.

In the drawings accompanying and forming part of this specification,

Fig. 1 is a diagrammatic sectional plan view of an apparatus embodying the features of the present invention;

Fig. 2 is a diagrammatic sectional side view, showing the apparatus vconnected with an amplifier and loud speaker, the housing elements being omitted; and

Fig. 3 is a fragmentary plan view of the record-carrying film, on an enlarged scale, and showing the film gate with its slit in position to permit passage of light through the record.

The same characters of reference designate the same parts in the different figures of the drawings.

Referring to the drawings, 1 designates a light source, from which the rays pass through condenser lenses 2 andthrough a slit formed in a suitable partition or screen 3. In the path of projection of the rays of light after their passage through slit is a focussing lens 4, by means of 'which said rays are focussed through a slit in the gate 5 upon a sound record 6 which has been photographed on a film, said film being adapted to travel past said slit in the'` usual manner. In the present instance the film and its gate are shown mounted at one side of a box`or housing 8 which is closed sov as to exclude all light except that which passesthrough the record carried by the film.

In the present instance, the interior of the housing is divided by a plurality of divergent partitions 9, 10, 11 and 12 respectively, so disposed that the converging ends of the outermost partitions 9 and 12 will confine between them all of the rays of modulated light that pass kinto the housing through the record 6, while the partitions l0 and 11 are so disposed between the partitions 9 and 12 as to split said light rays and causethem to travel through a plurality of diverging channels 13, 14 and 15. At the wider ends of the said channels are located light-sensitive elements such as photo-electric cells 16, 17 and 18 respectvely,each of said cells having its window of transparent portion so positioned as to catch the rays of light passing through one of said channels, the cells being, as usual, suitably connected to an amplifier 19 and loud speaker 20. In order reception of a maximum amount of the rays of light by each of the photo-electric cells, the surfaces of the partitions 9, 10, 11 and 12 forming the side walls of the channels 13,

14 and 15 are preferably reflecting surfaces.

or mirrors, as indicated in Fig. 1, said mirrors serving to reiect themodulated light rays entering between them back and forth until the rays kwithin each channel are received by the proper photo-electric cell,
